根据选定的日期范围计算工人的总小时数

Question

其他数据库：

您好，我想问一下如何根据所选日期范围计算每个工人 id 的小时总和，type5，type1，type2，type3，如图所示？

例如，我想计算从 2020-06-08 到 2020-06-21 的工人总小时数，结果是，

workerid    hour      type5     type1     type2     type3
04405     00:00:00  00:00:00  00:00:00   00:00:00  00:00:00
04408     12:00:00  02:00:00  00:00:00   08:00:00  02:00:00
04458     12:30:00  00:00:00  08:00:00   04:30:00  00:00:00

其中 04408 在日期范围内有 2 天，因此它将对小时求和，而 04405 在日期范围内没有任何 ot，因此返回 00:00:00

我将如何使用 sql 或 php，现在我创建一个 android 应用程序，谢谢

 <?php
include_once("dbconnect.php");

$sql ="with tempTable as (
select 
t.workerid,
sum(DATEDIFF(minute,0,t.hour)) hour,
sum(DATEDIFF(minute,0,t.Type5)) Type5,
sum(DATEDIFF(minute,0,t.Type1)) Type1,
sum(DATEDIFF(minute,0,t.Type2)) Type2,
sum(DATEDIFF(minute,0,t.Type3)) Type3
from othour t
group by t.workerid
    ) 
select 
t.workerid,
format(DATEADD(minute,t.hour,0),'HH:mm:ss')  as hour,
format(DATEADD(minute,t.Type5,0),'HH:mm:ss')  as Type5,

format(DATEADD(minute,t.Type2,0),'HH:mm:ss')  as Type2,
format(DATEADD(minute,t.Type3,0),'HH:mm:ss')  as Type3
from tempTable t";

$result= $conn -> query($sql);

if($result -> num_rows > 0) {
    $response["ot"] = array();
    while ($row = $result -> fetch_assoc()) {
        $ot = array();
        $ot[workerid] = $row["workerid"];
        $ot[othour] = $row["hour"];
        $ot[type5] = $row["Type5"];
        $ot[type1] = $row["Type1"];
        $ot[type2] = $row["Type2"];
        $ot[type3] = $row["Type3"];
        array_push($response["ot"], $ot);
    }
    echo json_encode($response);
} else {
    echo json_encode("error");
}

$conn ->close();

with tempTable as (
select 
t.workerid,
sum(DATEDIFF(minute,0,t.hour)) hour,
sum(DATEDIFF(minute,0,t.type5)) type5,
sum(DATEDIFF(minute,0,t.type1)) type1,
sum(DATEDIFF(minute,0,t.type2)) type2,
sum(DATEDIFF(minute,0,t.type3)) type3
from YourTable t
/*Where Conditions*/
group by t.workerid
    )
    
select 
t.workerid,
format(DATEADD(minute,t.hour,0),'HH:mm:ss')  as hour,
format(DATEADD(minute,t.type5,0),'HH:mm:ss')  as type5,
format(DATEADD(minute,t.type1,0),'HH:mm:ss')  as type1,
format(DATEADD(minute,t.type2,0),'HH:mm:ss')  as type2,
format(DATEADD(minute,t.type3,0),'HH:mm:ss')  as type3
from tempTable t
